Hello, this error indicates CMOS battery has failed or missing. Please check the battery socket has no residue and it's seated properly into it. You can try to replace CMOS(CR2032) battery. You can check this guide https://dell.to/3DeO72l;
After replacing the battery, you may need to clear the system event log (SEL) and reboot the server to see if the error message goes away. https://dell.to/46JpoRh
